4. Refer to the Circuit Diagram for quick pinpoint check. If you need to check circuit continuity between harness connectors in more detail, such as
when a sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout. Refer to Harness Connector.
5. When checking circuit continuity, ignition switch should be OFF.
6. Before checking voltage at connectors, check battery voltage.

FUSIBLE LINK
Fusible Link
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is questionable, use circuit tester or test
lamp.
CAUTION:
a. If fusible link should melt, It Is possible that a critical circuit (power supply or large current carrying circuit) is shorted. In such a case, carefully
check these circuits and eliminate cause of problem.
